Emma Green Tregaro posted this photo of her fingers on the social media site Instagram.

Anders Albertsson, the general secretary of the Swedish federation, said he didn’t know whether Emma Green Tregaro would repeat the nail-painting gesture for Saturday’s high jump final at Luzhniki Stadium.

Green Tregaro’s decision Thursday was a quiet criticism of a Russian law that bans so-called propaganda supporting homosexuality to minors. Russian pole vault star Yelena Isinbayeva said it showed disrespect to Russia.

“We have been informally approached by the IAAF. They were saying that this was by definition a breach of the regulations, not saying anything else, really,” Albertsson said. “We have informed our athletes about this.

“The impression one gets is that this came from her heart. I don’t think Emma thought this would be so big.”

Isinbayeva’s criticism of the Swedish athlete’s gesture attracted wide attention because she also said she supported Russia’s law and that Russians have “normal” heterosexual relations.

Isinbayeva said the next day she may have been misunderstood because she was speaking in English instead of her native language. She also said she is against discrimination.
